Top 10 Commonly Confused Words in Radiation Physics

Top 10 Commonly Confused Words in Radiation Physics 1. Ionization vs. Excitation Ionization and excitation are often used interchangeably, but they have distinct meanings. Ionization refers to the process of removing an electron from an atom, resulting in a charged particle. On the other hand, excitation involves raising an electron to a higher energy level without completely removing it. Both processes play significant roles in radiation interactions. 2. Absorption vs. Attenuation Absorption and attenuation are related to the interaction of radiation with matter. Absorption refers to the complete transfer of energy from the radiation to the material, resulting in its heating or other effects. Attenuation, on the other hand, is the reduction in the intensity of radiation as it passes through a material due to various factors like scattering and absorption. 3. Radioactivity vs. Radiation Radioactivity and radiation are often used interchangeably, but they have different meanings. Radioactivity refers to the spontaneous emission of radiation from a radioactive material due to its unstable atomic nucleus. Radiation, on the other hand, is the energy emitted in the form of waves or particles. Radioactivity is the source, while radiation is the emitted energy. 4. Dose vs. Dose Rate
